Low Power dual PIR Sensor
In order to extend the working hours of the camera battery, our
company has developed the low power dual PIR sensor based on the
original dual PIR infrared sensor. The low power dual PIR sensor
optimizes the accuracy and anti-jamming capability of the camera,
avoiding the mistaken shot and missed shot, and reducing the
camera's standby current. To save battery power, an Infer-Red
camera is in sleep/standby mode, with only the PIR sensor working.
When a person or an animal is detected by the PIR sensor, the
camera powers on and starts shooting, then it would enter standby
mode after shooting. The time period from being sensing animal to
taking the photos is called trigger time. The trigger time varies among
different scouting camera brands on the market, generally from 1 to 5
plus seconds. Our LTL ACORN scouting camera has an impressive
0.8 seconds trigger time. The shorter of the trigger timer, the higher
possibility to capture the animal.
Ltl-6511-4G (EXT.LCD) camera adopts the latest patented technology
of the Ltl Acorn,
horizontal dual-PIR (pyroelectric infrared sensor)
design, this solution has the following advantages:
1
、
Standby time is long. The camera uses the low power dual PIR sensor of
the latest R & D, reducing the camera's standby current to 60uA, which
greatly extends the camera's standby time.
2
、
Shorten the time required for shooting. The two side PIR sensors
come up with a 100 degrees angle of induction, it is far more than the
camera lens angle of 52 degrees. When the game reaches the side
PIR area, the camera powers on in advance and gets ready to shoot. If
the object continues into the overlapping area of left and right PIR
sensor, the camera takes pictures immediately, capturing the whole
body of the game. That process could be as short as 0.2 seconds.
Usually, when the game passes quickly, the traditional camera may
catch a part of it only, or nothing at all, while our camera can capture
the complete picture of the game.
3
、
Enhanced the camera's anti-jamming capability. As the camera is
placed in different environments, it may be subject to varying
electromagnetic interference. The camera uses a dual-PIR design,
only triggers to take picture when both sides of the PIR are detecting
the game, to avoid false shooting caused by insufficient capability of
anti-interference of single PIR.
